Overview
The Hermle C 650 is the largest machine in Hermle's performance line, built for shops that need serious 5-axis capability on big parts without sacrificing the accuracy Hermle is known for. With X/Y/Z travels of 1,050 x 900 x 600 mm, this machine handles workpieces up to 2,000 kg on a 900 mm diameter trunnion table. The modified gantry architecture keeps all linear axes in the spindle carrier while the workpiece only moves in A and C rotary axes, which is key to maintaining dynamic accuracy on parts this size.
The C 650 ships with an 18,000 rpm HSK-A63 spindle as standard, delivering 29 kW of continuous power for heavy cuts in steel and titanium. High-speed spindle options go up to 42,000 rpm for aluminum aerospace work. The 60-position tool magazine is expandable to 156 tools, and chip-to-chip time runs about 4.5 seconds. Rapid traverse hits 35 m/min on all linear axes. The mineral-cast base — Hermle's signature — weighs in at a total machine weight of around 16,500 kg.
Positioning accuracy sits at +/- 0.005 mm with repeatability of +/- 0.003 mm. Control options include Heidenhain TNC 640 or Siemens Sinumerik 840D sl. Hermle's HS-flex heavy pallet automation integrates directly for lights-out production. New pricing lands in the $650,000-$900,000 range depending on configuration. If you need Hermle quality on larger workpieces, the C 650 fills the gap between the C 52 U and the truly massive C 62 U.

Strengths & Limitations
Strengths
- Largest work envelope in the Hermle performance line — handles parts up to 2,000 kg
- Modified gantry design maintains dynamic accuracy even at this machine size
- Mineral-cast base provides outstanding vibration damping for heavy roughing
- 60-tool standard magazine expandable to 156 covers complex multi-operation parts
- HS-flex heavy automation system integrates seamlessly for unmanned production
- 18,000 rpm standard spindle with HSK-A63 handles aggressive roughing and fine finishing
Limitations
- Premium pricing puts it well above $650,000 — significant capital investment
- Large footprint requires substantial floor space and foundation planning
- Hermle service network in North America is thinner than DMG Mori or Makino
- 4.5-second tool changes are slower than smaller machines in the lineup
- Mineral-cast base limits machine relocation and foundation flexibility

Frequently Asked Questions
01
The C 650 has significantly more travel (1,050 x 900 x 600 mm vs 1,000 x 800 x 600 mm on the C 52 U) and double the table load capacity at 2,000 kg. It fills the gap between the C 52 U and the massive C 62 U.
02
New machines run $650,000-$900,000 depending on spindle selection, tool magazine size, and automation. Used machines from 2018-2022 trade in the $400,000-$600,000 range.
03
The HS-flex heavy pallet handling system is the primary automation option, designed for heavier workpieces. Full robotic loading cells are also available for complete lights-out capability.
04
Yes. The 29 kW spindle with HSK-A63 tooling and the mineral-cast base provide the rigidity and power needed for titanium roughing. The 2,000 kg table capacity handles substantial aerospace billets.
